With stringent environmental mandates governing the European Single Market, external power supply units (EPS) must comply with updated Ecodesign directives and voluntary EU Code of Conduct (CoC) Version 5 Tier 2 standards. For global B2B manufacturers exporting to the EU, ensuring power adapter compliance is vital to avoiding customs delays and market non-conformity penalties.
The EU CoC Tier 2 standard imposes demanding thresholds not only on full-load efficiency (100%), but crucially on 10%, 25%, 50%, and 75% load conditions, alongside an ultra-low no-load standby power consumption limit (< 0.075W). Traditional flyback converter topologies struggle to satisfy these multi-point load curves without substantial thermal energy waste.
To address this challenge, AUKRU has implemented digital quasi-resonant (QR) switching controllers coupled with advanced active clamp forward topologies. Under light loads, the adapter switches into a burst-mode frequency foldback, slashing parasitic capacitive losses and keeping standby consumption well below 0.05W.
All AUKRU commercial and industrial AC/DC adapters shipped to the EU market carry certified CE-LVD, CE-EMC, and ERP test reports issued by accredited test houses (TÜV Rheinland and SGS), ensuring seamless customs clearance and compliance peace of mind.
